Brown and Sharpe Taper Reamer: Straight shaft w/o spinning between centers.

Quick update... I cut facets in the reamer and it worked-out well. Since it's my first real utilization of the tool cutter/grinder, I'm going to skip those details -of the mindset that I do not wish to outline practices that I made-up on the fly. Suffice it to say, I used TDIs and just about everything else in the shop to set the angle properly and it seems to have worked. Basically, I eye-balled the amount of backside relief.

In order to test the angle, I whipped-out an aluminum hub with a rough internal taper done in the lathe then, reamed it by hand. The swarf packed up nicely in the cutting grooves and there was no backside rubbing. -And best of all, the hub fit on the spindle like a glove on the first shot. I feared I would end-up in the situation of getting it close then, nudging the angle, recutting the reamer and trying again. -I got lucky.

Doesn't it feel good when you figure something out, implement it, and then it just works?

How's the hand healing?
 
Yes, this was a nice surprise and those are always welcome. It was also nice to spend a few hours in the shop which I've vastly reduced to let the fingers get back on track. Two fingers are doing very well. Some numbness on them to varying degrees and the cut area is not toughened-up and is fragile but, basically doing well. The third finger still has the stitches and the pad part is basically a dead hunk of beef jerky. The dogs keep eyeing it... That one will be a slow heal. -Thanks for asking...

i know this thread is old, but i just wanted to say thanks for taking the time to show the different setups for turning tapers. I will be doing some MT3 tapers in the near future and this has helped a ton. thanks!
